G.I. Robot and War Machine

 

Robert Downey Jr. recently reiterated that his time as Tony Stark is indeed done, and he is not even planning to return for voice overs.  Does Don Cheadle still have movies on his contract?  This could be a good opportunity for War Machine  and James Rhodes to be more fleshed out in the movies as he will be the premiere Armored hero in the MCU going forward.
